AUTOMOBILE TORPEDO.

Application filed April 3, 1915.

To all "US/0777, it may concern:

Be it known that I, WILLIAM Dmrnn, a cititen of the United States, residing in the borough of Brooklyn, county of Kings, city immersion mechanism. The hydrostat has a diaphragm which on one side receives the water pressure and on theother side receives in an 2111' chamber the adjustable pressure of a spring. There is liability that the heat generated during the run may be sufficient tofbkp'ziaid the air in this chamber and cause it to 'exert a pressure against the diaphragm which adds to the pressure of the spring and opposes the hydrostatic pressure, so that it impairs the accuracy of the depth mechanism, having a tendency to cause the torpedo to run ata greater depth than that for which the hydrostat was set. To prevent such heating of the air, this invention provides a construction whereby a circulation of cooling water is maintained around the spring chamber to carry away any heat and prevent its reaching the air'in the spring chamber. v

Figure 1 of the accompanying drawings is a transverse'section of a'torpedo the plane of the section coinciding with the axes of water the springs and with the center of the diaphragm of the hydrostat; Fig. 2 is a fragmentary longitudinal section on a larger scale showing the water inlet.

'leferring to the drawings, A is the shell or hull of the torpedo, B the propeller shaft or shafts, and C as a whole the hydrostat which controls the depth or immersion mechanism. This hydrostat includes a 'dia phragm l) exposed on its lower side to a. chamber E which communicates through openings a a with the exterior water, the preferred construction including a. ring or annularframe b fastened to the shell of the torpedo, and a removable frame 0 fitting within the frame 7/ and having an annular disk porton to which the diaphragm is fastened by clamping its marginal portien between such annular part and a flange (Z made as part of an upright shell F Specification of Letters Patent.

chamber e. The shell F is formed with two cylindrical upright portions f f forming the spring chambers within which are inclosed the springs G G of the hydrostat, which springs react upwardly against plungers H H and press downwardly against an equalizing lever I, the middle of which has a rocking engagement at z with adisk It covering the middle portion of the diaphragm. To adjust the stress of the springs, the plungers H H are made adjustable by means of screwthreaded stems J J which are engaged by spindles j j having gears j at their upper end meshing with an intervening gear 70 fixed on an adjustingspindle Z which is accessible from the exterior and by which the adjustments of the two springs may be made simultaneously.

So far as described, the construction is that which is common in the Bliss-Leavitt torpedo. The specific construction is not essenti'al to the present invention and may be modified in accordance with any known or equivalent constructions used in practice.

The cooling means provided by the present invention will now be described. Surrounding'allor any part of the spring chamber or air chamber 6, is a water jacket K through which water taken from the exterior 'is forced to circulate. struction shown the jacket is not carried .to the bottom of the chamber so as to inclose all-of the shell F, but is confined to the individual shells f f inclosing the respective springs. The jacket is formed by surrounding each shell f with an outer shell L, so that the space between these cylindrical shells constitutes the water jacket K. Water is in- M and from the outlet M, tubes P P are provided which bridge the space between such inlet and outlet M M and inlet and outlet openings Q Q respectively formed through the shell of the torpedo and preferably at its upper part. Each opening Q. and Q is formed with a collar or neck 9," and with a hollow screw plug 1' screwing In the conwvithin the collar. The ends of the tubes P P enter into sockets m m beneath and n m above, and some suitable packing material isplaced in these sockets, as shown at p 72, to make Water tight joints. It is preferable to make the tubes P P with globular or substantially spherical end portions which form a sort of ball and-socket joint with the respective. sockets, so that even if the respective sockets are not perfectly .alined a tight joint Will nevertheless be made.

It is an advantageous feature of the in vention that in the assembling of the parts the hydrostat is first introduced and mounted Within the torpedo in any customary manner, and afterward the tubes P P are inserted from above through the collars 9, after which theupper packings p 7) are introduced and the nuts 1" r are screwed down. The assembling or disassembling of the parts is thus rendered very easy.

In order to force a circulation inward at the inlet side and outward at the outlet side, the inlet Q is provided with a head It which bridges over the opening and is turned forward, opening on its front side as shown in Fig. 2. The outlet opening may have a similar head turned aft, although it is quite "sufiicient to leave it uncovered. The head R is to be applied after the insertion of the tube and the screwing down of the plug. By reason of this head a sufiiciently active circulationof wateris maintained during all the time that the torpedo is under way.

This invention affords a simple and easily applied construction whereby to effectively cool the spring chamber and prevent the heating of the air therein, and hence has the effect of avoiding any abnormal action of the depth mechanism due to the pressure of such heated air against the diaphragm.

The invention is not limited to the precise construction shown, being'subject to a reasonable range of equivalents such as are Within the perception of those skilled in this art. I claim as my invention 1. In a torpedo, a hydrostat having a Water jacket around its spring chamber, tubes connecting from the inlet and outlet of such Water jacket to inlet and outlet openings in the torpedo shell, and a head applied to one of said openings to force a circulation through said tubes.

2. In a torpedo, a hydrostat havin a Water jacket around its spring cham 1,

said sockets to avoid leakage.

4. In a torpedo, a hydrostat having a water jacket around its spring chamber, said jacket formed with socketed inlet and outlet openings, the torpedo shell formed with inlet and outlet collars forming sockets, and removable tubes bridging between the inlet openings and outlet openings respectively, said tubes insertible through said collars, and perforated means for closing the openings in said collars after the insertion of said tubes.

5. In a torpedo, a hydrostat having awater jacket around its spring chamber, said jacket formed with socketed inlet and outlet openings. the torpedo shell formed with inlot and outlet collars forming sockets, and

removable tubes bridging between the inlet openings and outlet openings respectively, said tubes insertible through said collars, and annular screw plugs screwing into said collars against said tubes.

(S. In a torpedo, a hydrostathaving a water jacket around its spring chamber, said jacket formed with socketed inlet and outlet openin s, the torpedo shell formed with inlet and outlet collars forming sockets, and

removable tubes bridging between the inlet openings and outlet openings respectively,

the end portions of said tubes formed as balls fitting in the respective sockets, Whereby the tubes adapt themselves to any Want of alinement of the sockets, and fastening means for holding said tubes in place.

In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
